A patio is a paved outdoor area next to the house or in the garden, laid in porcelain, natural stone or concrete slabs on a compacted sub-base and mortar bed, with falls that direct rainwater away from the house.
Getting a new patio right in Wembley starts with understanding the house you already have: its age, how it was built and what has been altered over the years. We survey first, then commit on paper to a price that holds as long as the scope stays the same. Across London, guide prices run at £3,200–£7,200 including VAT, and homes in Brent, Harrow and Greenford are covered too.

How much does a new patio cost in Wembley?
Prices for a new patio vary from house to house, but in Wembley most projects fall within £3,200–£7,200 including VAT. That reflects costs in London, about 30% above the national guide. Treat the table as a budgeting aid; the written figure follows a survey we carry out for free.

Local housing and a new patio
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
So when we survey a Wembley property for a new patio, the first step is working out how it was built and what has been changed since.
Do you need permission in Wembley?
Wembley is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
A ground-level patio in a back garden does not usually need planning permission in England. Raised decks or platforms more than 30 cm high do.
Building Regulations do not normally apply to patios, but levels must stay below the damp-proof course and drain away from the house.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
We look at the job
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new patio, and photograph or measure anything the quote needs to reflect.
Your fixed price
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Dates and permissions
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new patio are in place before the first day on site.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
How we work
Common questions
How do you make sure water drains away from the house?
A patio needs a gentle fall, usually a little over 1 in 80, so rainwater runs away from the house towards the garden, a drain or a soakaway. The surface should also sit well below the damp-proof course. If the patio meets a door threshold, a channel drain may be needed. We set levels with string lines and check falls as we lay each section.
What should I do before the work starts?
Before work starts, clear garden furniture, pots and ornaments from the area and agree where materials will be delivered and stored. We need a route for wheelbarrows and, on larger jobs, a small digger, so let us know about side gates, narrow passages or access through the house. Tell us about any known drains, cables or pipes in the area.
Can you combine a new patio with other work?
Yes. Because we manage several trades under one contract, we can plan a new patio alongside other work on your Wembley home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
Does a patio need planning permission?
Most patios do not need planning permission, but it depends on the size, height and location, your home's position, whether it is listed or in a conservation area, and which UK nation you are in. Raised patios or decking more than a small height above the ground may need permission because of overlooking. We check the position for your garden before quoting.
